PUMP.

SPECIFICATION forming part of Letters Patent NO. 316,004, dated April21, 1885.

Application filed April 29, 1884. (No model.)

To all whom it may concern.-

Be it known that I, RUFUS M. BROOKS, a natural born citizen of theUnited States, residing at Greeley, in the county of Anderson and Stateof Kansas, have invented certain new and useful Improvements in Pumps;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawings, and to letters and figures of referencemarked thereon, which form a part of of this specification.

My inventionrelates to that class of pumps known as cattle-pumps, andhas for its object efficient, simple, and durable means whereby thecattle, sheep, horses, or other animals, on going to thewatering-trough, will pump water thereinto. To this end it consists inthe construction hereinafter described.

In the accompanying drawings, Figure 1 is a plan view; Fig. 2, a sideelevation. Fig. 3 is a rear elevation of a machine constructed accordingto my invention, and Fig. 4 is a detached cross-sectional view of thepreferred form of piston.

In carrying my invention into effect, I usually employ the cover A,which serves as a cover for the well or other water-supply, and as asupporting-base for the several parts presently described. On this base,near its rear end, I mount standards a, near the opposite sides of thebase. The upper ends of these standards are connected by the crossbar13, and support said cross-bar, as shown. This cross-bar is providedmidway its length with a vertical mortise, b, for the passage of thepiston-rod G, and is preferably provided with anti-frictionrollers D D,arranged on opposite sides of rod 0, within the mortise b, as shown inFigs. 1 and 3. The piston-rod extends below the base and into a suitablebox or cylinder, E, and is connected with a piston, F, and operates saidpiston within the box, as will be understood from Fig. 2. The piston Fis supplied with a suitable valve, f, so constructed as to permitpassage of water through the piston on the downward stroke of thelatter. The upstroke of the piston will force the water above it upthrough stock G, whence it will pour through spout 9 into the trough H,supported on the base and slightly in front of the standards, as shownmost clearly in Fig. 2. The box E, it will be understood, is submergedin the water whether in a well, cistern, or other source of supply, aswill be obvious.

It is evident that the piston F could be adapted and arranged to operatein the lower end of stock G where so desired.

Links I I are suspended from the cross-bar on opposite sides of thepiston-rod, and serve as pivotal supports for the levers J, which areprovided with a series of notches, j, into either of which the links Imay be adjusted to vary the length of stroke of piston, the force ofoperation, 850., as will be understood.v The inner ends of these leversJ are connected with the piston-rod, preferably by means of straps K,and their outer ends are connected by rods or links Z with one end oflevers L, the opposite ends of which are pivoted on suitable elevatedsupports, Z.

Hangers M are secured to the lever L near rear end of same, and supportone end of the platform N. Hangers m are suspended from the levers L,midway the ends of the latter, and are secured at their lower ends tothe levers O, at about the middle of said levers, as shown. The rearends of these levers O are pivoted on suitable support, 0, and theiropposite ends are pivoted at O to the platform. By this combination orsystemof connected levers I support platform N in such manner that it isalways in a true horizontal plane, and is equally depressed throughoutwhether the weight be equally or unequally disposed thereon. When thisplatform is depressed, it will be seen that the piston-rod, by means oflever L and the before-described connection, is raised and the waterpumped into the trough. This is effected by the cattle, sheep, or horsesgoing onto the platform N. On the animal leaving the platform thepiston-rod will be depressed to the position shown in Figs. 2 and 3 bymeans of weights connected therewith. These weights may consist ofstones held in a box mounted on the upper end of the pistonrod, as shownin Fig. 3, or may be suspended elsewhere on said rod, or the weights maybe dispensed within case the piston or its rod is made sufficientlyheavy to fall of its own weight when the weight on the platform isremoved.

The piston is provided with filling which is distended by coil-springs,to compensate for wear, as most clearly shown in Fig. 4.

Having described my invention, what I claim, and desire to secure byLetters Patent, is-

1. In a cattle-pump, the combination of the piston, the platform, thelevers L and O, the hangers MI and m, and means for connecting theplatform and the piston, substantially as and for the purposesspecified.

2. The combination of the piston-rod, the supporting-bar B, thedepending links I, the suspended levers J, having theirinner endsconnected with the piston-rod, and provided on their under sides with aseries of notches,

20 j, the platform, means, substantially as deouter ends of the leversJ, whereby the depression of the platform will effect the operation ofthe said levers, substantially as and for the purposes specified.

3. The herein-described cattle-pump, consisting of the pump-stock, thepiston with filling distended by springs, and piston-rod, the.supporting cross-bar provided with depending links, the levers pivotallysuspended in said links and provided with a series of notches wherebytheir pivots may be varied, the levers L, the links Z, the levers O,hangers M m, and the platform, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
